This happens when you're trying to use one of the panels such as "SceneGraph Inspector" in VSCode. Those panels work by having a small scenegraph "on-device-component" running inside your app. Right below that error, there should be instructions on how to enable that functionality.
- Set "injectRdbOnDeviceComponent": true in `.vscode/launch.json`
- Add the following comment in main.brs after calling screen.show(): ' vscode_rdb_on_device_component_entry
